Why it works
A linear equation is balanced as long as you do the same operation to both sides. Combining like terms and isolating x makes the balance explicit.
Common mistakes
- Distributing incorrectly before combining like terms.
- Moving a term across the equals sign without changing its sign.
- Treating identity or contradiction cases as if they had one numeric answer.
Worked examples
Distribute to get 2x + 6 = 14, then subtract 6 and divide by 2 to get x = 4.
Both sides are identical, so every x-value works.
Practice
- 3x + 5 = 20
- 7 - 2x = 1
- 6(x - 1) = 3x + 9
